Abstract
Description
Gebiet der ErfindungField of the invention
Diese
Erfindung stellt eine Verbesserung des am 23. Dezember 1997 erteilten
Beim Verfahren des Kaltwalzens von Stahlstab oder Stahldraht aus einem Walzblock durchläuft der Walzblock oder die Stange ein Mehrstufenkaltwalzwerk, in dem die Stange nacheinander zwischen je zwei Walzen durch läuft, welche die Stange quetschen, um in jedem Stich ihre Querschnittsfläche zu verringen.At the Method of cold rolling steel rod or steel wire from one Rolling block goes through the Rolling block or bar a multi-stage cold rolling mill in which the Rod runs successively between each two rollers, which squeeze the rod to reduce its cross-sectional area in each stitch.
Die Walzen sind auf widerstandsfähigen, freitragenden Ritzelwellen montiert, wo ein Rutschen zwischen Walze und Kammwalze beim Kaltwalzen nicht annehmbar ist.The Rollers are tough, cantilevered Pinion shafts mounted where a slippage between roller and pinion roller when cold rolling is unacceptable.

Zusammenfassung der ErfindungSummary of the invention
Die Erfindung beabsichtigt die Befestigung einer Walzwerkwalze auf einer freitragenden Kammwalze durch die Anwendung eines hydraulischen Druckmittels. Die Walze wird an einer vorgegebenen Montageposition auf die Kammwalze montiert und das hydraulische Druckmittel wird dann in einen vorgesehenen Hohlraum so eingefüllt, dass ein Gewindestöpsel sich seitlich aus seiner Anfangsposition heraus in den im Innern der Kammwalze vorgesehenen Hohlraum bewegt und somit den Durchmesser der Kammwalze vergrößert.The The invention is intended to mount a mill roll on a self-supporting combed roller by the application of a hydraulic pressure medium. The roller is at a predetermined mounting position on the comb roller mounted and the hydraulic pressure medium is then provided in one Cavity so filled, that a threaded plug sideways from its initial position into the inside the comb roller provided cavity moves and thus the diameter of the Scallop enlarged.
